All shirts are 100% cotton and hand-washable/hang dry (do not launder in machines). Simply remove the driver unit and cables from the inside of the shirt.
Drivers use 2 easily-replaceable AAA batteries. Shirt is 100% cotton, available in adult sizes SMALL through XXL (XXL has a $3 size surcharge.)
Please note: Unlike our normal E-shirts and EL shirts, this tee has a sewn-on design and thus the design panels and drivers from our regular E-shirts and EL shirts are NOT interchangeable with the Mega design EL Shirts.
